Abstract
Description
Technical Field
[0001] The utility model relates to the field of geological exploration, in particular to a recoverable guide reaming deflector. Background Art
[0002] Geological drill pipe is an indispensable tool in geological exploration and coal mining drilling operations. Its primary functions are to transmit torque, transport drilling fluid, deepen the wellbore, and bear the weight of the drilling process. Manufactured through a friction welding process, geological drill pipe possesses high strength and rigidity, effectively transmitting the rotational torque of the surface drill rig to the drill bit, driving it for rotary drilling. Furthermore, the drill pipe is equipped with internal channels that transport drilling fluid to the bottom of the well, cooling the drill bit, carrying drill cuttings, and stabilizing the wellbore wall. By drilling holes on the surface or underwater, it can penetrate deep underground to obtain samples of rock, soil, water, and other materials, providing critical data and basis for geological surveys, resource assessments, and engineering design.
[0003] During the operation of geological exploration drill rods, accidents such as rod breakage, drill loss, connector breakage, or the appearance of unexplored local rock layers at the drilling location often occur. These accidents cause the original drilling location to be blocked or make it difficult to continue drilling downwards. The only option is to re-plan a drill rod route, which leads to the recalculation of various costs such as manpower, materials, and machinery, resulting in unnecessary losses. Utility Model Content
[0004] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a recyclable guide reaming deflector.
[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:
[0006] The utility model discloses a recyclable guide reaming deflector, which includes a rod body. The rod body is generally cylindrical and has a connecting section at one end, a base at the other end, and a deflecting section in the middle. The connecting section is hollow and annular, and a connecting groove is provided on its inner wall. A smooth transition groove is provided above the deflecting section, which gradually shrinks from the connecting section toward the base and is in a conical shape. The bottom end of the base is a closed opening.
[0007] As a preferred technical solution of the present invention, the connecting groove is an internal thread surface, and the internal thread surface is coupled with the external thread surface of the male joint of the geological drill pipe.
[0008] As a preferred technical solution of the present invention, the outer diameters of the connecting section and the base are consistent with the outer diameter of the geological drill rod, and the inner diameter of the connecting groove can allow a geological drill rod one size smaller than the above-mentioned geological drill rod to pass through.
[0009] As a preferred technical solution of the present invention, the outer diameters of the connecting section and the base are consistent with the outer diameter of the geological drill rod, and the inner diameter of the connecting groove can allow a geological drill rod one size smaller than the above-mentioned geological drill rod to pass through.
[0010] As a preferred technical solution of the present invention, the inner diameter of the starting position of the smooth transition groove is consistent with the inner diameter of the connecting section.

[0013] 1. This utility model is transformed from geological drill rods, which greatly reduces the cost of casting new products;
[0014] 2. By setting a smooth transition groove with a tapered shape that gradually tapers from the connecting section toward the base above the deflected section, the secondary geological drill rod is forced to deviate vertically along the deflection angle of the smooth transition groove. This can avoid difficult drilling locations, open up new drilling paths, and widen the existing borehole diameter.
[0015] 3. The connecting section is coupled with the male joint of the geological drill pipe, so that when the geological drill pipe is pulled out, the deflector is also pulled out, achieving the purpose of recycling and reuse, reducing operating costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.
[0023] In the drawings, the same reference numerals all refer to the same components.
[0024] like Figure 1-4 As shown, the utility model provides a recyclable guide reaming deflector, which includes a rod body 1. The rod body 1 is generally cylindrical and has a connecting section at one end, a base 4 at the other end, and a deflecting section 3 in the middle. The connecting section 2 is hollow and annular, and a connecting groove 21 is provided on its inner wall. A smooth transition groove 31 is provided above the deflecting section 3, which gradually shrinks from the connecting section 2 toward the base 4 and is in a conical shape. The bottom end of the base 4 is a closed opening.
[0025] In the present invention, the rod body 1 is modified from a geological drill rod, so some parameters are the same as those of the geological drill rod. The interior can be hollow casting or solid casting, and hollow casting is preferred here.
[0026] In an optional embodiment, the connection groove 21 is an internal thread surface, and the internal thread surface is coupled to the external thread surface of the male joint of the geological drill pipe.
[0027] It should be noted that, by coupling the connecting groove 21 with the male joint of the geological drill rod, when the geological drill rod is pulled out, the deflector is also pulled out, thereby achieving the purpose of recycling and reuse.
[0028] In an optional embodiment, the outer diameters of the connecting section 2 and the base 4 are consistent with the outer diameter of the geological drill rod, and the inner diameter of the connecting groove 21 can allow a geological drill rod of a smaller size than the above-mentioned geological drill rod to pass through.
[0029] It should be noted that, since the rod body 1 is modified from a geological drill rod, different types of geological drill rods can be modified into corresponding rod bodies 1 , and the interior of the connecting section of the rod body 1 is large enough for a geological drill rod of a smaller size to pass through.
[0030] In an optional embodiment, the inner diameter of the starting position of the smooth transition groove 31 is consistent with the inner diameter of the connecting section 2 .
[0031] It should be noted that it is necessary to ensure a smooth transition of the geological drill pipe from the connection section to the deflection section 3.
[0032] In an optional embodiment, the length of the connecting section 2 is 300 mm to 500 mm, the length of the deflecting section 3 is ≥ 1500 mm, and the length of the base 4 is 50 mm.
[0033] The working principle of the present invention is as follows: the connecting section 2 is connected to the male joint of the geological drill rod, and through the end-to-end connection of multiple geological drill rods, the drilling rig is operated to lower the deflector to the designated location. After the deflector is placed, the next type of geological drill rod is operated by the drilling rig to pass through the inside of the above-mentioned geological drill rod, and then pass through the inside of the connecting section 2 and contact the smooth transition groove 31. Under the continuous pressure of the drilling rig, the next type of geological drill rod is forced to deviate vertically along the deflection angle of the smooth transition groove 31 until the next-level geological drill rod passes through the deflection section 3, bypassing the obstacle or expanding the aperture.
[0034] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
